Genovieve Grouios MEd

FOUNDER · MATHEMATICS EDUCATOR AND AUTHOR

Genovieve has spent over fifteen years inside primary and secondary mathematics classrooms — teaching children, coaching teachers, and rebuilding whole-school mathematics programs from Foundation to Year 10. She also spent seven years in universities, training the next generation of teachers.

She has written mathematics curriculum at state and national level. But those aren’t the accomplishments she counts. For Genovieve, reaching even one student is a great accomplishment — the moment a child lights up because an idea finally makes sense. Numbers only matter to her when they mean more children are actually learning. Her mission is to give the gift of understanding to all children — not just the privileged few.

She has sat beside hundreds of children at the exact moment mathematics stopped making sense to them. She has seen, up close, where the standard approach loses a child, and why more worksheets never bring them back. And she has seen something the system rarely admits: children don’t need years of repetition to understand a topic. Deep understanding comes early, and comes quickly, when a child is given the right tools and the right way to think.

That is why Linear Abacus exists. Built with Dr Andrew Waywood and grounded in his twenty years of mathematical research, everything in it — every activity, every conversation, every book — was built from what actually helps a child understand numbers, tested across years of real classrooms and homes.

Now she brings that knowledge to the place where it works best: one parent and one child, side by side, with the time, patience and love to explore.

Dr. Andrew Waywood

Principal Advisor 

Dr. Andrew Waywood is a long time mathematics educator academic, now retired. For over ten years Andrew has
been developing and trialling a language arts approach
to teaching arithmetic.

Many of the ideas were trialled in pre-service teachers training courses. He has written academic papers on the connections between children’s learning language and how this interacts with learning arithmetic as well as presenting at national and international conferences.

He believes that teaching language and teaching maths have a common 
core which is teaching to ‘make sense’. He formulated the idea of a PIC (a pedagogical image of a concept) – which actively connects doing, saying, and calculating – as a schema for classroom communication that meets the deeper curriculum requirements of students becoming problem solvers. 

Shirley Houston 

Mathematics Tutor

Shirley Houston is an independent Educational Consultant based in Perth, Western Australia. She has a Masters degree in Special Education and has worked for over 40 years in the areas of diverse needs and inclusive education, at primary, secondary and tertiary level. 

Her particular interest is specific learning difficulties such as dyslexia and dyscalculia. She works with students, parents, schools, homeschoolers and companies that are developing products to support students in literacy and numeracy. She also runs online courses and webinars and onsite training for teachers. She advocates for research-based, systematic, multisensory instruction for all students.

S​éverine Sors

French Translator

Séverine Sors is an international educator with over 25 years 
of experience in primary, secondary, and higher education across Belgium, France, England, and Australia.

She is a UK qualified teacher and holds a Master’s degree in English 
from Sorbonne Nouvelle, as well as a Master’s in Education. Her extensive experience encompasses teaching in private, state, and Steiner education settings.

In particular, she has worked in primary schools in Brussels, Belgium, 
where she effectively instructed students in French. Additionally, her role 
in a Melbourne-based bilingual primary school was instrumental in shaping her pedagogical approach, allowing her to implement innovative teaching strategies and curriculum development tailored to diverse learning needs. 

This experience has been a significant foundation in her preparation for a Master of Teaching, where she aims to further enhance her skills and contribute to the educational landscape.

OUR MISSION

Every child deserves to understand mathematics — not just perform it. That is the only reason Linear Abacus exists.

Join Our Community

Mathematics makes more sense when you have someone to talk it through with. The Linear Abacus community is a space for parents, teachers, and educators who want to go deeper — sharing what works, asking what doesn’t, and learning alongside each other.
